Tel Aviv University researchers have made a discovery that could enhance our understanding of genetic mutations and their role in brain development. The study, "Protective inherited mutations in activity-dependent neuroprotective protein (ADNP): the good, the bad, and the ugly," published in Genomic Psychiatry , reveals that not all genetic mutations are harmful—some may actually offer protection against developmental disorders. Led by Professor Illana Gozes, Director, The Elton Laboratory for Molecular Neuroendocrinology, the research team identified a protective inherited mutation in the Activity-Dependent Neuroprotective Protein (ADNP) gene.
This finding challenges the traditional view that genetic mutations in ADNP invariably lead to developmental challenges. "I was struck by how this particular mutation actually enhanced certain protein interactions, potentially offering protection against developmental disorders ," explains Dr. Gozes.
"This discovery opens up entirely new perspectives on how we view genetic variations and their impact on brain development." The study focused on a unique case where a mother carrying an ADNP mutation showed above-average adaptive behavior, while her child, inheriting both this protective mutation and a second variant, demonstrated better outcomes than typically seen in similar cases. Key findings include: What makes this finding particularly intriguing is how it might influence our approach to genetic therapy.
Could other seemingly harm.
